Bordeaux - South African flyhalf Tian Schoeman suffered a triple jaw fracture in Bordeaux's Top 14 victory over Agen on Saturday and will be out of action for three months.
The 26-year-old was taken from the pitch after 26 minutes after a collision with Agen's George Tilsley left him groggy.
It is the third injury loss in recent weeks for the side lying sixth in France's Top 14 after Jayden Spence with concussion and Simon Hickey, with knee ligament damage, joined the sick bay.
